Popis:	Alkaline-earth doped LaCoO3 has been found to be promising as conductive oxides instead of standard metals for use as electrodes. Electrical conductivity has a maximum, σ = 4.4 × 103 S cm−1, in La0.6Sr0.4CoO3. We believe that the increase in mobility was caused by the decrease in the Co–O bond length.
